(遼寧工程技術大學土木與交通學院，阜新123000)[摘要] 在我國的各類礦山以及礦山相關企業(yè)中，存在著大量的鋼筋混凝土結構。這些結構大部分長期承受小能量、高頻次的沖擊、磨損以及化學腐蝕等作用，導致其迅速失效，進而導致礦山企業(yè)產量下降，維修安全性降低。本文以試驗為基礎，研究了沖擊速度與鋼筋混凝土結構磨損量的關系，得出了鋼筋混凝土結構的沖擊磨損量與磨料的動量成正比的結論，確定了相關系數。為今后礦山中此類鋼筋混凝土結構的設計、施工等方面工作提供相應的依據。

(Liaoning Engineering and Technology University, Fuxin 123000, China)Abstract: There are lots of reinforced concrete structures in mining area. Under the collision of little amount of energy, great frequency, attrition wear and chemical denudation, the reinforced concrete structure will inactivate quickly. It lead to the volume of production fall down and maintenance exposure increase. In the paper, on the base of test the relation of velocity and wearing capacity was studied. It proved that reinforced concrete structure wearing capacity direct ratio to abradant momentum and the coefficient of association was determined. These achievements supply corresponding experience for design and execution ofreinforced concrete structure.
Keywords: reinforced concrete structure; attack wear; momentum; wearing amount; coefficient of association
